From the looks of it, you have a lot of slow but hard hitting Pokemon. They would REALLY appreciate paralysis support. But right now I want to look at your Tyranitar...
Just a few words about Tyranitar, I would not use Outrage without STAB and the speed something like Salamence has because it is quite risky and it gets easily revenge killed by the likes of things like Lucario or Scizor. If you really want to nail dragons, just get something like Ice Punch instead (but Stone Edge works better thanks to STAB). Instead, I would replace Outrage with Fire Punch so that you can nail Scizor on the switch, who likes to switch into Tyranitar quite often. It is also a safe move to use if you are bad at prediction, for many things that switch in can be hit super effectively like Scizor, Heracross, Mamoswine, Metagross, Bronzong, Lucario and such, and it even has that 10% chance of burn (of course, you still have to watch out for boosting Heatran's Flash Fire or giving Heracross the burn which = doom). As for Earthquake and Aqua Tail, both are quite redundant in coverage. Sure, Aqua Tail is much safer because nothing in OU aside from Vaporeon is immune to it (would you be fighting Vaporeon with Tyranitar anyways?) and being locked into Earthquake is not a good idea, but Earthquake and Aqua Tail pretty much covers the same types of Pokemon. I would replace one of them with Stone Edge. Yeah, I HATE Stone Edge because it misses everytime I want it to hit and the other guy always nails me with it and critical hits me, but you get the point. It provides better coverage and takes advantage of STAB, and not many things like to take Stone Edge from Swampert. Even 248 HP Scizor can take around 94% damage max from it (~ 80%ish minimum) when equipped with Choice Band, so it can OHKO with Stealth Rocks. Now which one to replace? If you want to 2HKO Gliscor with Aqua Tail then stick with Aqua Tail. Otherwise Earthquake is more reliable and does more damage usually but being locked into it giving the opponent a free chance to switch in is no fun.
As for that EV spread... 4 HP/252 Atk/252 Speed... there is not much thought put into it. 252 Speed on Tyranitar hits 221... which really does not outpace anything but those minimum speed Skarmories and Scizors (who spam Bullet Punch anyways) and other Tyranitars, so it really serves no purpose (not to mention so many Pokemon specifically hit 222 speed JUST to beat Adamant Tyranitar or hit 244/245 Speed just to beat Jolly Tyranitar's 243 speed... and everything else is naturally faster than Tyranitar WITHOUT any investment). If you really want to outpace Skarmory and those other Pokemon sitting around 180ish range, hit 88 Speed EVs to tie with them at 180 Speed (assuming 31 IVs), or raise it even higher up to 92 or 96 tops... but that is pretty much all this Tyranitar needs. Tyranitar is hopelessly slow so it wants all the defense it can get, so pump the rest into HP.
Another EV spread I found useful is 252 HP/40 Atk/216 SpDef with Careful nature. It can take on Gengar's Focus Blast and KO back with Crunch (Focus Sashers still die to the sand stream) and sponges hits from Latias (Draco Meteor does like 30%ish if I am not mistaken) and Zapdos (lol at ~18% Thunderbolt damage, 9% Heat Waves, and ~19% Hidden Power Grass) quite well to absorb their hits. Crunch eats both of them up and none of them wants to stay around long enough to let Tyranitar destroy them. Earth Power from Heatran is 3-4HKO at best while Tyranitar's Earthquake OHKOs it back. But using this set, I would not use Aqua Tail because it will not 2HKO Gliscor, its main target, due to that low input in Attack. But let's face it. With Tyranitar's already monstrous attack, does it really need much investment? Which one will you use? 160 HP/252 Atk/96 Speed Adamant or 252 HP/40 Atk/216 SpDef Careful? It depends on your playing style, but 4 HP Tyranitar is not taking a Bullet Punch from Scizor, which runs around everywhere.
Yeah, also another thing about what randomspot said: would Tyranitar's sandstream hinder your team a lot? That Gyarados with Life Orb will NOT like the sand at all. So think about your team synergy and maybe it will work out for you, but somehow Tyranitar somewhat collides with your Dragon Dance Gyarados. Maybe if that Gyarados was the Leftovers type with a bulkier EV set it might work. But then again without Gyarados there is not many people who can take down Scizor, and bulkier Gyarados does that job quite well. You may need to consider replacing Gyarados or Tyranitar with something or work around it. Also, Tyranitar does NOT counter Suicune. Suicune can do a good job messing around with Tyranitar, despite Tyranitar's bloated Special Defense. The Resttalk versions with Calm Mind and Surf (Crocune) can do an even greater job messing around with Tyranitar, bypassing that special defense boost and 2HKOing-OHKOing with Surf after a few CMs. If you are lucky and get a Defense Drop from Crunch though, Suicune can be beaten but they usually switch out only to come back again and mess with it. Also as randomspot said, a spinner can help. My choice of spinners are Forretress and Tentacruel (the former due to its bulk and crazy Gyro Ball and the ability to set up all entry hazards and the latter because it eats Toxic Spikes and counters Mixapes very well). Good luck with your team.
